I was wondering how to check clock speed before making adjustments on one my co-workers AMD Radeon RX570 GPUs
This is the command you run, it will output the current clock frequencies
cat /sys/kernel/debug/dri/0/amdgpu_pm_info
this is my card
GFX Clocks and Power:
1750 MHz (MCLK)
1286 MHz (SCLK)
96.125 W (VDDC)
16.0 W (VDDCI)
123.228 W (max GPU)
124.227 W (average GPU)
GPU Temperature: 76 C
GPU Load: 100 %
other option is to run amdgpu-pro which gives you a lot of info
/opt/amdgpu-pro/bin/clinfo
This is what the output looks like

You should always check before and after you make change to your GPUs. It’s important to always keep your GPU temperature low. This is running a little hotter only because it’s in a case. Another good reason to go with an open air mining rig.
